Re: HMI 575 vs MSD 575??
Perhaps in linking the two posts in general concepts for general idas.
"Some of the things to work out would be:
Lamp
base fitting; you'd need to make the lamp fit & be secure
Lamp size; does it fit in the
current space provided, is it too long or too short & would it focus correctly.
Lamp temperature; is it much hotter than the
current lamp and if so will the extra heat cause issues with lenses, light path, moving elements (
douser/
shutter, gobos
etc.)
Voltage/
Power supply; can the
current power supply drive the different lamp
FYI, there's a great post on the Blue Room about different lamp types! link
Good luck !:"
Lamp
base secure, are we talking about modifying the
fixture for a different lamp? That would be a bad thing amongst issues arc gap.
HMI (or HTI), HMD, MSR and MSD lamps while not
ANSI coded for similarity are normally made to between brands fit into the same fixtures in being competive. They compete with each other for that when an apples to apples question. At times for certain lamps, there is no similarity due say to fill pressures, but in these above cases - there is no real difference between products overall. The HSR verses MSD question is apples and oranges as would be a HSD verses MSR question. Normally what the lamp is doing MSR/MSD or HSR/HSD won't
effect the
fixture. Also, both versions are normally interchangable for
voltage etc. issues. Glad to see Blue room is still out there.
Getting into specifics, there is no such thing as a
HMI 575. While some really old pamphlets had me taking notes on it as a G-22 based lamp, it was only pamphlets. Assuming the
HMI 575 above is in question comperable to a MSD 575,
MSD 575 Philips #27479-5 CL, HP. SE. MH.
HID., 575w/95v T-30mm 8mm arc gap
LCL 65mm GY 9.5 75
CRI (Universal Burn Pos.) 207v Min. 5,900°K 45,000 Lum 2,000hr
The similar product from Osram would be the:
HSD 575w/72 4ARXS Osram #54129 CL, SE. MH.
HID. Non-HR 575w/88v T-30mm 7mm arc gap
LCL 65mm GX 9.5 Any Burn Pos. (
CRI 85) 7,200°K 45,000 Lum 3,000hr
Have not checked the philips website in the past two years for this lamp, might be the same.
Moot
point, you have a "Design Spot 575" but left out a lot of important info Phillips "MSR 575/2 SADE" These are not
ANSI coded lamps so you really do have to not simplify what you want info on. MSR Gold™ 575 SA/2 DE is the proper description
MSR Gold
7.5K in color temp, 39,000 Lumens initial, 750 hour.
Perspective MSD 575 dual ended version of the lamp is not listed on the Philips website but could exist. Can check further with my contacts but doubt there is a say MSD 575SA/2DE, but possible.
Assuming that it is a MSR 575SA/2DE lamp, I'm out of date in my notes for such lamps but I am sure GE, Philips and Osram are well competive in the same versions of this lamp at this
point. That is the concept in making the same lamps to compete with, they are mostly the same, just about price and end results overall for quality.
Hope it helps, I can if wanted look further into this issue but think mostly solved.
